All you need is an internet connection to watch catch up TV from the likes of SBS on demand, Seven plus, ABCiView, and you don't need a 'Smart' or Internet connected TV.

The news comes as Sydney and Melbourne prepare to turn off analog transmission completely next month.

Freeview says 'Plus' is one of the most important developments in its five year history, and will launch in the first half of 2014. FreeviewPlus is one of the worlds first services to combine free-to-air broadcast TV with broadband.

14 million watch live Free to air networks like Seven and Nine but 1 in 4 are now watching catch up TV said Liz Ross, General Manager of Freeview.

"Catch up TV will be part of a new range of services Freeview and the free-to-air networks will introduce next year."
